STAR RUBY Dark red color is characteristic of this variety, even when grown in cooler coastal regions. Crop heavy in spring, stores well on the tree. Both skin and flesh are red. It is less vigorous than other varieties, grows slowly and the tree and fruit remain smaller than other grapefruit types.
However, in suitable conditions the tree produces attractive red blushed fruit. The flesh and juice are strongly pigmented, up to three times more colourful than 'Ruby Red', and have a bit more sugar and acid. The fruit is low-seeded or seedless and has a very good flavour. Juice content 43% at maturity.
